I’m a 130 pound female and was able to put this together. And as long as you follow the directions, it’s not too difficult to put together. There are a few pieces that if they don’t fit perfectly ,you want to flip and they fit better. As for the shipping a few pieces of the metal were bent as expected, but I easily bent them back. The only reason I am giving four stars instead of five is because one of the pieces where the holes were supposed to be drilled, the machine did not drill them all the way through. It was easy enough for me to just re-drill the holes because I could see where they were marked at but I know not everyone will have the tools to do that when you purchase something that you don’t expect to need them for. All in all, though I love the shed for the price.
